Abstract
PURPOSE:To improve safety by arranging a number of sound collection devices in an engine section to detect sound of the engine section and record it as a data and making warning to be issued when the engine is abnormal. CONSTITUTION:In an engine compartment of an aircraft, ship, automobile, electric generator, etc. are arranged a number of sound collection devices A and their output signals are inputted via a level control device B and discrimination device C into a calculator E. In the discrimination device, the input signal is compared with a reference value from a reference device D. In case abnormality, in any position of the engine section is detected with the calculator E, a warning device is actuated to inform the occurrence of the abnormality while the detected result is recorded as a data.
